position to the glass portion of a show win` dow in such a way that different colored lights may be successively projected upon an advertisement in order to attract attentioih and to make the advertisement more impressive and effective.A

Another object of the invention 1s to provide'a device which may be readily made and which may be sold at a comparatively small cost.

A further object of the invention is to provide a device in which the advertisement may be placed directly upon the window and the colors projected thereon, and in which the heat from the lamp producing the light will also serveto operate a part of the device having the means for changing the colors on the advertisement.

A still further object of the invention is to provide simple and eiiicient means whereby the device may be supported upon an ordinary incandescent electric bulb so as to bc rotatable thereon.

With these and other objects in view,the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be ointed out in the claims at the end of the cscription.

llnfthe drawings, Figure 1 is a plan view of one form of device embodying my'invention. Fig. 2 is a longitudinal section of the device, partly in elevation, taken on the line llli-II of Fig.' 1. Fig. 3 is a fragmentary if? detail plan view of a 'part of the supporting Fi 4 is a. transverse section taken* bracket. on the line V-IV ofFig. 3,'showing the means whereby the bracket may be used to 'engage an electric lamp socket and to support the-lamp thereon. Fig. 5 is a sectional plan view through the means for changing the colors on the advertisement, said means in this case being in the form of a c linder; and Fig. 6 is a plan view-'on a smaller scale showing the device `differently located from that shown in Figs. 1 and 2.

The window may have the usual plate.

glass 10, and mounted thereon in any suit able way is a body 11. This vbody contains the advertisement to be displayed, and may be produced by printing, lithographin'g or otherwise on a thin transparent or translucent or other body, or by transfer means if desired. The body or advertisement 11 may be of any desired form and size andlo cated convenient thereto, in this case under the same, is abase 12. The base l2 may be cemented or otherwise held to the glass' 10 on the inner surface thereof, and in said base are two openings or recesses which are en gaged by the downwardl bent ends 13 of a supporting bracket 14. he base 12 may be of wood, porcelain or any other material and the bracket 14 may be made of wire and in a single piece. This bracket has two arms 15 which lie in substantially the same lane, and at or near the outer end thereo is a socket 16 substantially cylindrical in form. From the socket 16 project arms 17 each of which has'an upturned and substantially V- shaped end 18. The reach rods 17a of the arms or supporting members 17 diverge outwardly and the ends 18 thereof are-adapted to support a shade. 19 whichmay bev of opaque material, as paper, or may be inthe form of a reflector if desired. 'lhisvshade or member may have a slitted portion forming a band 20 which is adapted to tit over any one of the ends 18 of the supporting members 17 of said bracket, or the said shade 19 'may be held thereto ferred manner.

A lam socket21 may be connected to any suita le source or" electric supply, and

in any other presaid socket. has a reduced portion 222 as 10G usual, which is adapted to tit into the socket portion 16 of the bracket 14, said socket portion being formed as a part thereof a d extending downwardly, as at 23, so as o serve as a bearing means for the socket. The- 105 rods 15 of the bracket 14 may be held together by a device or clip as 24 so as to clam hold the lamp socket, and this clip has a part 25 pivoted to one of the rods 15 land has a spring portion Q6 to tit about or partly 11'0 pensed with and the spring of the reach provided with a central bearingportion 35 readily rotate thereon.

TheV lamp socket cairies the usual globe 28 from which projects the usual teat 29 which in this case forms a bearing for a device 30. This device 30 is in the toi-in ot a cylinder though it may be polygonal or any other desired forni, and said device is adapted to thi ow different colors of light upon ,the advertising body or element ll. The device 30 has a plurality of panels 31 and these panels may l-all dider in color as red, white, blue and yellow, and each panel may be made up of a series of colors, as `for example the ,upper part being red, the center blue, an theelower part yellow, thesev colors alternating with respect to the colors of the other panels so that when the device ,30 is rotated, as will be presently described, 'theseyc'olors will be successively projected upon the 'advertisement l1. The panels 31 forni a part of a cylinder which may be divided by st-rips 33 both on the inside and outside thereof to separate one panel Afrom tthe other, and said cylinder may be of glass,

translucent ,material through which the light may be projected on tp the advertisement 11. y 1

Theupper end of the cylinder 30' may be provided With a cap 34. and this cap may be of metal or of any other suitable material adapted to it over the teat 29 of the lamp. globe or bulb 28 'so that the saine may I A series of blades 36 extend radially from the'center toward the outer surface of the cap and these blades are so formed that the heat from the lamp will create sufficient circulation of air through the cylinder so that as the saine passes the blades, the device 30 will rotatel about the lamp, thus causing the `dittercnt colored lights to be projected on to the ad-` vertisement, the shade 19 or reflect-or if' made in this `forni"beingapositioned to protect the rest of the window or to shade other be projected only iiivNh/ere it is wanted. In Fig. 6,'the construction is substantially the same as that already described, except may be' secured by screws or otherwise to a wood portion 39 of the window.` This forni of device is used where it is not convenient or advisable to cement or otherwise attach the b ase directly uponkthe glass. In this V case, the shade or the reflector may be .sup-

ported on one o': the sideU supporting menibers l1 of the bracket instead of in the man f ner shown in Figs. l and 2.

lt will be understood that other means than an electric lamp may be used for lighting purposes as well as means to rotate the light projecting device.

From the foregoing, it will be seen that a,

simple, eiiicient and eti'ective device is pro vided whereby advertising mattei' may he displayed upon the show window; that said device is simple in construction rnd is inexpensive to manufacture; that lsaid device may be readily placed in position; that the advertising matter' may be changed at will and of any suitable character to indicate the goods to be displayed; and that said device may be readily made and placed in position for use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l.
